A travel backpack that fails on a single flight is one too many — zippers jam mid-gate, laptop compartments lack padding, or the bag itself refuses to fit under the seat. The right bag solves all of that before you ever leave home, turning chaos into organized, hands-free transit through airports, train stations, and city streets.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I research travel gear obsessively, analyzing compartment layouts, fabric durability, harness ergonomics, and airline compliance to separate true travel backpacks from bags that only look the part.
After comparing dozens of models across capacity, organization, and real-world carry comfort, these recommendations represent the strongest options available today for anyone searching for the best backpack for traveling.
How To Choose The Best Backpack For Traveling
The single biggest mistake travelers make is buying a bag based on looks alone — ignoring the real metrics that determine whether that bag will serve you through long security lines, tight overhead bins, and multi-day packing needs. Three factors dominate the decision.
Capacity Range and Expandability
A fixed 25L bag works for a day trip but fails on a weekend away. Look for a backpack that expands from roughly 35L to 45L, letting you compress it for underseat storage and open it up when you need to pack a jacket or extra shoes. Models that grow 10L or more give you flexibility without forcing you to carry a second bag.
Laptop Compartment Design
A standard sleeve is not enough. Quality travel backpacks use a suspended or raised laptop pocket that keeps your device from hitting the ground when you set the bag down. Side or rear zipper access to the laptop compartment also matters — you should never have to dig through packed clothes to reach your computer at TSA checkpoints.
Security and Access Features
Lockable zippers, hidden stash pockets, and RFID-blocking compartments add real protection during crowded travel. Also consider the luggage pass-through — a horizontal strap that lets the backpack slide over your suitcase handle — which is essential for navigating terminals without carrying the bag on your shoulders the entire time.

In‑Depth Reviews
1. Peak Design Travel Backpack 45L
The Peak Design Travel Backpack 45L is the gold standard for one-bag travel. It expands from a compact 35L to a full 45L using a simple internal zipper system, and the rear, side, and top access points mean you can reach your gear without unpacking everything. The 400D recycled nylon canvas shell with a premium DWR coating shrugs off rain, and the burly #10 UltraZip is among the most durable zipper systems on any travel bag.
Internally, the bag is organized with multiple mesh pockets, a dedicated laptop sleeve that fits up to 17-inch machines, and side pockets that expand to hold water bottles or a travel tripod. The shoulder straps and hip belt tuck away completely, turning the bag into a streamlined duffel for overhead bin storage. The luggage pass-through and 360-degree grab handles make terminal transitions effortless.
For travelers who pack efficiently and want a single bag that handles everything from a weekend to a two-week trip, the Peak Design offers unmatched versatility. The sternum strap can be fiddly to connect, and taller users may wish for longer shoulder straps, but the build quality and thoughtful design make this the bag most urban travelers should start with.
Why it’s great
- Expands from 35L to 45L without losing carry-on compliance
- Weatherproof shell and reinforced bottom handle heavy use
- Hidden external carry straps and tuck-away harness streamline airport movement
Good to know
- Shoulder strap length may feel short for taller users
- Stowable hip belt is minimal and not ideal for heavy loads
2. Osprey Daylite Expandable 26+6 Travel Pack
The Osprey Daylite Expandable 26+6 is the bag that fits under the seat of almost every airline. At just 1.85 pounds and sized as a personal item, it expands two inches to add six liters of storage — going from a 26L daily pack to a 32L travel pack that holds a change of clothes, a 15-inch laptop, and travel documents. The AirScape backpanel keeps your back ventilated during long walks through terminals.
Build quality is classic Osprey — bluesign-approved recycled polyester with a PFAS-free DWR finish, YKK zippers, and reinforced stitching. The front zip pocket holds quick-access items, two stretch water bottle pockets keep hydration handy, and a luggage pass-through lets it ride on your suitcase handle. The laptop sleeve is accessed via a dedicated rear zipper, which keeps your computer accessible without opening the main compartment.
This bag excels for international travelers who want to avoid checked bags entirely. The 26+6 fits under seats on budget carriers like Ryanair and Spirit while still packing enough for a three-day trip. The only compromise is that expanding to 32L pushes it tight on some airlines’ personal item dimensions — use the expansion only when you need it.
Why it’s great
- Meets personal item dimensions for most airlines even when expanded
- Lightweight construction doesn’t waste capacity on heavy materials
- Dedicated laptop zipper allows quick TSA access without unpacking
Good to know
- No hip belt — heavier loads rely entirely on shoulder straps
- Expanded 32L size may not fit under seats on smaller regional jets
3. Briggs & Riley Medium Cargo Backpack
The Briggs & Riley Medium Cargo Backpack bridges the gap between a professional briefcase and a travel pack. The three-section design separates a tech compartment (fits up to 15-inch laptops) from the main storage and quick-access front pockets, so you never have to rummage for your tablet when your laptop is buried. Top-grain leather handles and a navy nylon exterior give it an executive look that works in boardrooms and airports equally well.
Security is a priority here — the hidden back pocket is perfect for a passport or wallet, and an RFID-blocking compartment protects credit cards and IDs. The SpeedThru pocket on the front lets you grab headphones or a boarding pass without opening the main zipper. A built-in sunglasses pouch and key fob add daily-use convenience, and the luggage pass-through slides securely over a rolling suitcase handle.
The biggest trade-off is the side water bottle holder, which is too narrow for standard 32-ounce bottles — you’ll need a slim 16-ounce option. The bag is also heavier than some competitors due to the premium materials and structured shape. But Briggs & Riley backs it with a lifetime repair service, and the build quality justifies the investment for frequent business travelers.
Why it’s great
- Lifetime repair service covers damage from normal use
- RFID pocket and hidden back compartment enhance travel security
- Professional aesthetic with durable nylon and leather accents
Good to know
- Side water bottle holder is too narrow for standard 32 oz bottles
- Heavier than similarly sized bags due to structured design and materials
4. Thule Landmark Backpack 40L
The Thule Landmark 40L is built for travelers who prioritize security without sacrificing organization. The covert CashStash compartment is hidden under the SafeZone — a padded area designed to keep valuables like passports and cash away from pickpockets. The LoopLocks system secures zipper pulls directly to the bag, adding another layer of theft deterrence that is rare in this price range.
The main compartment opens fully for easy packing, and the internal divider keeps clean clothes separate from dirty gear. A dedicated laptop sleeve fits 15-inch MacBooks, and a padded tablet pocket holds up to 12.9-inch devices. The bag is lightweight for its capacity — around 2.5 pounds — and the adjustable harness system provides decent load distribution for urban walking.
Some users report that the bag lacks a quick-access outer pocket for small items like phones and snacks. The material is not fully waterproof — it handles light rain but zippers are not sealed — so you may want a rain cover for extended wet weather. For travelers moving through crowded cities who worry about theft, the Landmark’s security features are a genuine differentiator.
Why it’s great
- CashStash hidden pocket and LoopLocks zipper security deter theft
- Lightweight construction at approximately 2.5 pounds for a 40L bag
- Internal divider organizes clean and dirty items separately
Good to know
- Lacks an accessible outer pocket for quick phone storage
- Not fully waterproof — zippers are not sealed against heavy rain
5. BlackVoyage Vortex Vacuum Seal Travel Backpack 60L
The BlackVoyage Vortex rethinks packing efficiency with a built-in air compression system that vacuums clothes down to a fraction of their original volume. At a full 60L expandable capacity, this bag can hold a week’s worth of clothing in a carry-on-sized footprint — the compression bags are integrated directly into the main compartment, so you don’t need separate packing cubes or rolls.
The exterior is water-resistant with a professional black finish, and a built-in TSA lock secures the main zipper. Internal organization includes a padded laptop pocket, multiple mesh dividers, and side pockets for water bottles or accessories. The shoulder straps are adjustable and padded, though the bag’s structure leans toward the heavier side when fully packed.
The compression system works best on soft clothing like t-shirts, sweaters, and pants — bulky items like boots or puffy jackets will still take up significant space regardless of compression. The rubber cover on the charging port has been reported to detach over time. For travelers who pack densely and want to maximize carry-on capacity, the Vortex is a unique and functional solution.
Why it’s great
- Integrated air compression system reduces clothing bulk by roughly 50%
- TSA lock adds security for checked and overhead bin use
- Water-resistant exterior protects contents in light rain
Good to know
- Heavier than standard packs when fully loaded due to compression hardware
- Rubber charging port cover may detach with frequent use
6. Tolaccea Travel Backpack 40L-50L
The Tolaccea Travel Backpack offers three carrying modes — backpack, duffel, and sling — from a single bag. It expands from 40L to 50L via a center zipper, and the wet/dry compartment keeps gym clothes or toiletries separate from the main storage. The suspended laptop compartment fits up to 15.6-inch devices and absorbs shocks when the bag is set down hard.
TSA-friendly side access to the laptop sleeve lets you grab your computer without opening the main compartment. The luggage pass-through works with standard suitcase handles, and the chest strap and padded mesh back improve comfort during long carries. The tear-resistant polyester exterior and SBS lockable zippers hold up well to frequent travel.
The bag feels heavier than some competitors due to its reinforced structure and multiple carrying accessories. The crossbody strap is stored in the water bottle pocket, which takes up space you might want for hydration. For travelers on a tighter budget who want convertible functionality and expandable storage, the Tolaccea delivers solid quality at a compelling price.
Why it’s great
- Converts between backpack, duffel, and sling for versatile airport use
- Wet/dry compartment isolates damp items from clean clothes
- Suspended laptop sleeve protects devices from impact
Good to know
- Heavier than dedicated travel packs due to multi-mode hardware
- Crossbody strap stored in water bottle pocket reduces usable hydration space
7. BANGE Business Smart Backpack
The BANGE Business Smart Backpack proves that entry-level pricing does not have to mean flimsy construction. The high-density coated Oxford fabric is genuinely waterproof and scratch-resistant, making it a reliable choice for daily commutes and short overnight trips. The main compartment fits four to five changes of clothes, and the laptop pocket offers 180-degree opening for easy access to a 15.6-inch machine.
YKK zippers glide smoothly, and the multifunction shoulder strap includes a built-in card slot for quick ID access. The front pocket is large enough for shoes or an umbrella, and the glasses hang hook keeps eyewear within reach. At 2.65 pounds, it is relatively lightweight for a bag with this much structure, and the padded back panel provides adequate comfort for moderate loads.
The bag does not include a luggage pass-through or expandable capacity, so it is best suited as a commuter pack that occasionally doubles as a travel bag. The charging port version exists but this particular model (Black, no Charge Port) skips that feature. For travelers who need a durable, waterproof backpack for daily use that can also handle a short trip, the BANGE delivers exceptional value.
Why it’s great
- Waterproof Oxford fabric keeps contents dry in heavy rain
- 180-degree opening laptop pocket simplifies access during security checks
- Lightweight construction at 2.65 pounds for a fully structured pack
Good to know
- No luggage pass-through for suitcase stacking
- Not expandable — capacity is fixed at roughly 28L
